Definitions

  • the present invention relates to a tape reel and, more specifically, to a tape reel for use with a video cassette.
  • the conventional tape reel for use with a video cassette consists, as shown in FIG. 1, a lower reel member 1 having a hub 2 and an upper reel member 3 which are assembled with each other by fitting plural number of protrusions 2a formed on the hub 2 of the lower reel member 1 into holes formed in the number corresponding to that of said protrusions 2a in the upper reel member 3, and then fixed to each other by fixing the protrusions 2a by a means such as ultrasonic welding.
  • Such a conventional example had a defect that it requires a large number of manufacturing stages since welding of the upper and lower reel members is necessary after they have been assembled. Further, it had an additional defect that the reel members may be deformed at the welding stage, thereby making it impossible to manufacture tape reels with high precision.
  • a general object of the present invention is to provide a tape reel comprising a lower reel member consisting of a disc-like flange and a hub which are made integral and a disc-like upper reel member, said two members being fixed to each other by fitting protrusions having claw-like heads formed on either member into holes formed in the other member.
  • FIG. 1 shows a sectional view illustrating the construction of the conventional tape reel
  • FIG. 2 shows a sectional view illustrating the construction of an embodiment of the tape reel according to the present invention
  • FIG. 3 shows a sectional view illustrating the construction of another embodiment of the present invention.
  • FIG. 4 illustrates a plan view showing details of the construction of the lower reel member of the Embodiment 2;
  • FIG. 5 illustrates a plan view showing details of the construction of the upper reel member of the Embodiment 2.
  • FIG. 6 illustrates a sectional view taken along VI--VI in FIG. 3.
  • FIG. 2 shows a sectional view illustrating the constructions of the main parts in the Embodiment 1 of the present invention wherein shape of the protrusions formed on the hub is different from that of the conventional tape reel shown in FIG. 1.
  • the embodiment is different from the conventional tape reel in that the former has claw-like heads 13a on the tops of the protrusions 13 on the hub 12 of the lower reel member 11.
  • FIG. 3 shows the Embodiment 2 of the present invention wherein the protrusions for fixing the upper and lower reel members are formed on the upper reel member.
  • protrusions 15 are formed on the upper reel member 14', whereas holes to be engaged with the claw-like heads 15a of the protrusions 15 are formed in the cylindrical circumferential wall around the hollow portion 21 of the hub 17 of the lower reel member for inserting a driving shaft.
  • the upper and lower reel members are assembled and fixed by inserting the protrusions into the holes to compose a tape reel in the procedures similar to those described with reference to the Embodiment 1.
  • groove 18 having a definite depth d is formed in the circumferential wall 17a with notch portion 19 left for fixing a tape as shown in FIG. 4, and slots 20 are further formed at constant intervals so as to form holes 22 which pass from the groove 18 to the hollow portion 21 of the hub 17 for inserting a driving shaft.
  • Thickness t 1 of the side 17b of the hub to be brought into contact with the upper reel member is larger than the thickness t 2 of the flange on the side of the reel. Therefore, the protrusions 15 of the Embodiment 2 are longer than the protrusions 13 in the Embodiment 1. In the embodiment 2, therefore the protrusions are flexed more easily and have lower possibility of breakage in assembling and fixing both the upper and lower reel members. In the Embodiment 2, it is not always necessary to form the groove as shown in FIG. 3, but will be sufficient to form holes for engaging the protrusions only at the portions for inserting the protrusions.
  • a driving shaft has three protrusions within the range to be inserted into the hub, slots 21a are formed at the intermediate portion of the hub as shown in FIG. 6 for fitting the above-mentioned protrusions of the driving shaft.
  • the driving shaft is a simple cylinder in the section from its intermediate point to the tip.
  • the holes are formed in the slots (generally three or its integral multiples)
  • the heads of the protrusions engaged with the holes are not brought into contact with the driving shaft, thereby assuring advantage in practice.
  • Shallow slots will be sufficient in such a construction.
  • such a construction makes it possible to reserve a long distance longitudinally from the surface of the hub to be brought into contact with the upper reel member to the holes. This therefore permits protrusions 15 to be longer so that they can be flexed more easily.
  • the tape reel according to the present invention does not require welding or similar means for fixing the upper and lower reel members which instead can be assembled and fixed to each other simply by forcibly fitting protrusions formed on the upper or lower reel member in the holes formed in the other reel member so as to compose a tape reel. Therefore, the present invention can remarkably simplify the stage of assembling the reel members without fear of degradation of manufacturing precision due to deformation.
  • the embodiment 2 of the present invention makes it possible to design longer protrusions which can be flexed larger and have lower possibility of breakage, thereby permitting fixing both the reel members more strongly.
